In a recent article in Harvard Business Review, Marc Freedman, founder and CEO of Encore.org, and Trent Stamp, CEO of The Eisner Foundation, make a compelling case for the benefits of mentorship in societies facing aging populations. Freedman and Stamp, members of the Milken Institute’s Center for the Future of Aging advisory board, cite research showing that older people who mentor younger people are three times as likely to be happy as those who don’t, and provide examples of programs that bring generations together for mutual benefit. In addition to the economic benefits it brings, “helping young people to learn, while keeping older people vital, is a recipe for social cohesion.”
